Failed maneuvers exam - retry in 2 months.. advice?

After 12 hours of lessons (license A), I failed my maneuvers exam.. I had a slow start but at the end of my lessons I was able to do the whole exam without problems when practicing at the driving school, but on the exam itself I guess stress got to me and I blew it.

I just called the driving school I did the exam with to plan my next try and to my surprise, I have to wait until April to do the maneuver exam again! My instructor said I would be able to plan a new one quickly so this came as a surprise and also as a huge kick in the teeth.

I have planned a 2 hour lesson the day before, and then 1 hour right before the exam because I am afraid I will have forgotten a lot in 2 months of no riding. Even with those 3 hours I am afraid of that.

Does anyone have any advice for what to do in this situation?

I really want to get my license so this stings a lot.
